I've just begun scraping, had a few hours private lesson with Rich and it has done me wonders.
I've successfully scraped a prism to ~40ppm, and I've scraped the bottom of my compound and cross-slide to 20 ppm. Rich got the bottom of the saddle done while he was at my place helping me. I still have to do the compound base, the compound dovetails, the cross-slide dovetails, and the saddle top.
At this point I think I have a general idea but just want a double-check.
#1 I'm going to scrape the dovetails on the non-gibbed member of the compound (sliding member) to be parallel (using a King-way clone or similar fixture & the prism).
#2 Then use that as a master for scraping the opposing member, starting with the flat ways, then the non-gibbed dovetail, then the gibbed dovetail, and finally the gib itself.
#3 The order on the saddle will be a bit mixed because the saddle is longer, and the gib is in the cross-slide. I'm going to scrape the cross-slide bottom, then use that & straight-edge to get the saddle flats, then get the saddle dovetails parallel, and finally the dovetails & gib on the cross-slide.
Am I on the right track?
Side question, I'm going to make a diamond hone for the scraper blades. I have an 11:1 gear reduction box that I can put on an 1800 or 3600 rpm motor and end up at 327 or 164 rpm. Is that too slow for a hone?
